275 vs 315 Tires
The difference between a 275 tire and a 315 tire lies in their width. The 275 tire size is 275 millimeters wide, while the 315 tire size is 315 millimeters wide. This means the 315 tire is 40 millimeters wider than the 275 tires.
275 vs 315 Table
This comparison table provides a quick and easy way to understand the differences between two tire sizes.
| 275 Tire Size | 315 Tire Size |
|---|---|
| More comfortable ride | Maximum traction on dry roads |
| Generally less expensive | Better handling performance |
| Better traction in snow, rain, and slush | Suitable for heavier loads |
| Better fuel economy | More attractive appearance |
| Recommended rim width range: 8 to 10 inches | Recommended rim width range: 9.5 to 11.5 inches |
| Smaller than 315 tire size by 40 millimeters | Larger than 275 tire size by 40 millimeters |
| Can replace 315 tire size (shared rim width range) | Can replace 275 tire size (shared rim width range) |
Gas Millage
Generally, opting for wider tires (315) over narrower ones (275) can result in reduced fuel efficiency. Wider tires produce greater rolling resistance and friction with the road, demanding more engine power to maintain speed.
If fuel economy is your main concern, narrower tires might be a better option. However, if handling and aesthetics are more important, the minor drop in fuel economy with wider tires could be acceptable.
Ride Comfort
Ride comfort varies significantly between the two sizes. The 315 tires, with their broader sidewall, absorb impacts more effectively, offering a smoother ride on rough terrains.
On the other hand, 275 tires, being narrower, tend to provide a more comfortable experience on highways and city roads due to their reduced rolling resistance.
Ground Clearance
Ground clearance is enhanced with 315 tires, making them a preferred choice for off-road adventures or navigating through rugged terrains.
Conversely, vehicles equipped with 275 tires might find it challenging to overcome obstacles, leading to potential undercarriage damage.
Aesthetics Look
Aesthetics differ markedly; 315 tires offer a more aggressive and visually appealing look but may compromise aerodynamic efficiency. Meanwhile, 275 tires contribute to a sleeker, more aerodynamically friendly vehicle profile.
Handling & Stability
Handling and stability are influenced by tire size; 275 tires provide enhanced handling and quicker response on paved surfaces. In contrast, 315 tires deliver improved stability and traction, especially in off-road conditions or on uneven surfaces.
Noise & Vibration
Noise and vibration are further considerations; 275 tires are generally quieter on smooth roads but may transmit more vibrations from road irregularities.
The larger 315 tires might generate more noise, particularly with aggressive tread patterns, but can also offer a dampened ride due to their increased air volume and sidewall height.
Durability & Wear
Durability and wear patterns differ; 275 tires may exhibit more even wear and potentially longer tread life. The 315 tires, while capable of enduring more impacts, may introduce additional wear on vehicle components due to their increased weight.
What Does 315 Mean On A Tire?
The number 315 on a tire refers to the tire’s section width, which is the measurement in millimeters from sidewall to sidewall when the tire is mounted and inflated on a rim.
In other words, it’s the widest point of the tire when viewed from above. So a tire with “315” in its size code means that it has a section width of 315 millimeters.
The tire size code is usually found on the tire sidewall in a standardized format such as “P315/40r22” or “315/35r20.” The other numbers and letters in the size code indicate other important tire characteristics such as aspect ratio, construction type, rim diameter, load index, and speed rating.
What Is 315 Tire Size In Inches?
The 315 tire size refers to the width of the tire in millimeters. Specifically, a tire with a 315 size has a width of 315 millimeters. To convert this to inches, you would divide the width in millimeters by 25.4 (the number of millimeters in an inch).
Therefore, a tire with a 315 size is approximately 12 inches wide (315/25.4 = 12.40). However, it’s important to note that tire sizes also include other measurements, such as aspect ratio and rim diameter, so the overall size of the tire is more complex than just its width in inches.
How Much Wider Is A 315 Tire Than A 275?
Assuming that you are referring to the tire’s width in millimeters, the 315 tire is 40 millimeters wider than the 275 tires.
More specifically, the 315 tire has a width of 315 millimeters, while the 275 tire has a width of 275 millimeters. Therefore, the difference in width between the two tires is: 315 mm – 275 mm = 40 mm.
How Much Taller Is A 315 Tire Than A 275?
If we assume that the aspect ratio and wheel diameter of both tires are the same, let’s consider an example of tires with an aspect ratio of 75 mounted on 16-inch wheels.
Their sizes can be denoted as 315/75r16 and 275/75r16 respectively. To calculate the overall tire height, we use the formula: (height of sidewall x2) + rim diameter = overall tire height.
Using this formula, we can determine that the 315 tire size has an overall height of 34.6 inches, while the 275 tire size has an overall height of 32.16 inches. This means that the 315 tire size is approximately 2.36 inches taller than the 275 tire size, assuming both have the same aspect ratio and wheel diameter.
